Seco 17002635 Square End Mill 0.028 in 4 Flute Carbide

Product Description

The SECO 17002635 is a solid carbide square end mill designed for high-precision milling in demanding metalworking applications. Part of the ME430 series, this single-end tool features a 0.028-inch cutting diameter and a 0.084-inch length of cut, making it well suited for fine detail work, slotting, and profiling in tight geometries. The 4-flute, right-hand spiral configuration with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. Micrograin carbide construction provides the rigidity and edge retention required when machining hard or abrasive workpiece materials. The bright, uncoated finish is appropriate for applications where coating is not required or may interfere with tolerance control.

This end mill is intended for use in CNC machining centers and manual mills where small-diameter precision tooling is required. Its centercutting capability allows direct plunge entry into the workpiece. Compatible primary workpiece materials include steel, stainless steel, cast iron, aluminum and non-ferrous metals, and high-temperature alloys. The straight cylindrical shank measures 0.125 inches in diameter and fits standard collets and tool holders used in precision milling setups across aerospace, medical device, mold-and-die, and general metalworking environments.

Key Features

• 0.028-inch cutting diameter with a mill diameter tolerance of plus or minus 0.0005 inches for tight dimensional control
• 4-flute, right-hand cut and right-hand spiral flute design with a 30-degree helix angle
• Centercutting geometry allows direct plunge milling without a pre-drilled entry point
• Micrograin solid carbide construction for superior hardness and edge retention
• Bright, uncoated finish suitable for a wide range of workpiece materials including aluminum and high-temp alloys
• ME430 series single-end design with a straight cylindrical shank for standard collet compatibility

Compatibility

Designed for use with standard collet systems accepting a 0.125-inch straight cylindrical shank. Suitable for machining steel, stainless steel, cast iron, aluminum and non-ferrous materials, and high-temperature alloys as designated by material codes P, M, K, N, and S.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank fully into the collet and verify runout does not exceed the maximum TIR of 0.0001 inches before beginning a cut. At this diameter, proper speeds and feeds are critical — consult the tooling manufacturer's recommendations for the specific workpiece material to avoid tool breakage.
